Loads of people still go into work whilst ill; many of them because they have to / because there are financial penalties if they don't (especially with gig labour).
My point though is whether those thousands of deaths that we treat as just one of those things are preventable, and specifically whether if we had a proper test and trace system (like SK and Taiwan) whether we'd be able to use it to prevent those deaths. If we could, without any economic penalty (beyond the cost of maintaining the system) then I think its something we absolutely should do.
Okay, I agree on that second part.
What can we do about people going to work when they're ill, though?
And how do you define when someone should or should not go to work?
You can't can you, because different people fight things off differently - or are more susceptible to certain illnesses than others. So how do you control that? Where would the cut-off be?
I totally understand in regards to something like COVID, where it can be tested for. But I'm not sure how an everyday bug - which ultimately is what can cause/lead to flu or a bad illness - can really be tested, tracked and traced?
